摘　　要：恩恢264是湖北省恩施自治州农业科学院用自育强优恢复系恩恢58作母本,恢复系多系1号作父本杂交选育而成的中籼迟熟恢复系,具有持久抗稻瘟病、恢复力强、配合力高、株叶型好等特点,用该恢复系所配组合Ⅱ优264综合表现优良,于2006年4月通过湖北省农作物品种审定。Enhui 264, developed from the cross of two restorer lines Enhui 58 as the female and Duoxi 1 as the male by the Hubei Enshi Prefectural Academy of Agricultural Sciences, is a new late-maturing medium indica restorer line in rice. It is characteristic of durable blast resistance, strong restoring ability, high combining ability and good plant type. The hybrid combination II You 264 （ II - 32 A/Enhui 264） performed well in integrated characteristics and was certified and released to commercial production by the Hubei Provincial Crop Variety Appraisal Committee in April, 2006. Some other new hybrids derived from Enhui 264 such as Zhongyou 264, Jinyou 264 and You I 264, showed also high yielding ability and moderate blast resistance in various yield trials.
